Question

 

 

Hello Doctor,

I've been wondering if it is normal for my eyes to change from brown to very light green when I'm exposed to sun.

When I was a little girl my eyes were light grey but when I grew up they changed to green for a few years than turned to dark brown but every time I go out in the sun light they change automatically to green and the more I'm exposed to the sun the lighter they become.

And it's making me really worried. Now I can see some green in my eyes mixed with brown but they keep on changing I don't know why. I really want to know is it normal?

Thanks

Thanks for your Question

It is normal for the color of the eye to change under sunlights. The color of the eye is determined by the amount of melanin pigments in the iris. Iris is a thin, circular tissue inside the eye that is responsible for the color of the eye and responsible for controlling the size and diameter of the pupil. 

In sunlights, the pupil constricts and the iris stretches and the melanin pigments also stretch over a larger area and the color of the eye appears to become lighter in color. In dark room or dim light, the pupil dilates and the iris shrinks and all the melanin pigments shrink into small area and the color of the iris appears to become darker in color. So what you have is normal and there is nothing to worry about.

Iris melanin pigments increase with exposure to sunlights, the same as the color of your skin becomes darker when you expose to sunlight but in the eye this will be permanent. Children are usually born with light eye color but for many reasons in which exposure to sunlight is one of them, the color becomes darker as they grow older.
